In the wake of the 33-year-old athlete’s DUI arrest on Friday, Aug. 30, a source tells E! News exclusively “Khloé and the family are urging Lamar to seek treatment.” (A rep for the Kardashians could not be reached for comment.)

The 29-year-old E! star has been focused on “getting Lamar better,” a source says, but is hoping Friday’s arrest “will be his wake-up call.”

“Khloé has been trying so, so hard to keep him from hitting a bottom like this,” adds the source. “But if this is what needed to happen, then this is what needed to happen.”

Everyone in the Kardashian/Jenner clan is pulling for Lamar, but a source says Khloé only recently told the family about her husband’s substance abuse struggles. And despite persistent but untrue rumors of a Khloé and Lamar split, a source says “everyone in the family feels divorce should be the last option.”

Kim Kardashian was admittedly “shocked” to learn of her brother-in-law’s drug problem, says a source, but she “would like to see [Lamar and Khloé] work it out…She knows how much they love each other.”Follow @Infocelebrity on Twitter!
